This page is for data modellers who want to connect to an external database, either to load data or to export processed data back to it.

Overview

A datasource is a modelling object whose properties provide the information needed to connect to an external database. You

must have one datasource for each type of database to which you need to connect.  In an analysis model, you can add:

• a Database Collector to load data from a database.
• a Database Exporter to update the database with processed data from the model.

The datasources you create appear in the Basic Settings → Datasource list in collector and exporter properties.

Each datasource must have at least one datasource instance. You can add several instances if you want to configure different settings. For example you may want to connect to the same database using a different username and password for different scheduled tasks. 

In the properties for collectors and exporters, you can optionally specify the datasource instance using the Advanced → Datasource Instance Expression.

To add a new datasource to an analysis model:

1. Go to the model's toolbar → Create group.
2. Click

   Insert excerpt
   _database _database nopanel true

    to expand the menu.
3. Drag a 

   Insert excerpt
   _datasource _datasource nopanel true

    onto the analysis model.

To add an existing datasource to an analysis model, in the model diagram toolbar:

1. Go to the model toolbar → List group.
2. Click

    to expand the menu.
3. Click 

   Insert excerpt
   _datasource _datasource nopanel true

    to open the list of available datasources.
4. Drag a datasource into the analysis model.
